Frequently Asked Questions

What purity standard do your compounds meet?

All compounds are verified at ≥98% purity via reverse-phase HPLC with mass spectrometry confirmation. Every order ships with a lot-specific Certificate of Analysis (COA) documenting the exact purity, identity, and testing methodology for that production lot.

Do you include a Certificate of Analysis (COA) with every order?

Yes — every single order. The COA is lot-specific, sourced directly from the manufacturer, and corresponds to the exact lot shipped to you. We also maintain a publicly accessible COA Library on our website where you can download COAs by SKU, compound name, or lot number.hodology for that production lot.

What payment methods do you accept?

We accept Visa, Mastercard, American Express, Zelle, ACH bank transfer, and Paypal. All card transactions are processed through a secure, PCI-compliant payment processor.

How fast do orders ship?

Most orders ship within 1–2 business days. Domestic orders ship free via USPS Priority Mail with full tracking. All orders are packaged in insulated, discreet packaging designed for transit protection of lyophilized powders.

Do you offer bulk or wholesale pricing?

Yes. Purchasing 5 or more vials earns one free 5mg vial of your choice. Orders of 10+ vials unlock wholesale pricing tiers. For institutional purchasing or high-volume orders, contact us directly for custom quotes.
